MEANS FOR SECURING CONDUCTOR-TERMINALS. I

Patented Dec. 3, 1912.

Application led May 20, 1912. Serial No. 698,463.

To all whom 'it may concemf Be it known that I, GEIgALD W. HART, a citizen of the United States, residing at Vest Hartford, county of Hartford, y'State of Connecticut, have invented certain new and useful Improvements in Means for Securing Conductor-Terminals, of which the following is a full, clear, and exact description.

My invention relates to means for securing conductor terminals, and has for its object to provide a means whereby the vibration of the conductor is distributed so as to be largely removed from the immediate proximity of the binding post.

In certain relations, particularly in connection with switches upon automobiles, the conductors are' subjected to an intense and long continued vibration. If this vibration is no-t prevented, and is not distributed, its effect is so pronounced in close proximity to the binding postl that the conductor crystallizes and in time breaks at that point.

The object of my invention is to provide a means for distributing this vibration so as to largely prevent itin close proximity to the binding post, which means is simple and convenient and permits the use of insulated wires of various' sizes. The following is a description of an einbodiment of my invention, reference being had to the accompanying drawings, in which- -v Figure l is a side elevation of a switch, having my improved means. Fig. 2 is a rear elevation of the same; Fig. 3 isv an end elevation of the same,- with the conductors omitted. Fig. 4 shows a plan and end view of the'spring clip used.in embodying my invention. Fig. 5'. is axplan and end view of a clamp .used in said spring clip.

Referring more particularly to the drawings, 1 is the faceplate of a push button switch, 2 -is its casing, 3 is the base carrying binding posts 4 to which theconductors 5 5. of the circuit to be controlled are connected. i

Heretofore considerable annoyance and inconvenience has been experienced due to the crystallization and breaking of the conductors 5 adjacent to the binding posts 4, on

account of the vibration of the conductors when the switch has been used upon automobiles, or inother relatlons where the conand then are respectively-clamped beneath.

the heads of the screws of the binding posts 4. The internal diameter ,of the smaller ends of the sockets 8 and 9 is sufficiently small to closely grip the insulation 10 upon any conductor which lwould be likely to be used in making the circuit. If the insulation 10 is larger than may be deemed necessary by some, the conductor can nevertheless be forced through the tapered sockets 8 and 9, the sockets yielding as the conductor is pressed in through The clip 6 with its sockets 8 and 9 gripping the conductors will prevent, to a large Aextent, the vibration of the conductor adjacent to the vbinding posts 4, and distribute it. through a considerable length. If it is desired to'have the sockets 8 and'9 grip the conductors very firmly so as to hold them more securely in place, an additional cla-mp 11 may be applied, this clamp being held in position by a sc ew 12 passing through another hole in t e clip 6 and entering the face plate 3. This clamp 11 when forced downward by the screw 12 causes the sockets 8 and 9 to contract so that the smaller ends ofthe sockets grip thev respective conductors very firmly.

from the larger ends.

As'will be evident to ,those skilled in the n art,"the invention permits of modification lng post and a yielding socket having its axls in line with said'binding post.

2. In a means for securing insulated circuit conductors, the combination of a spring clip and a' binding post in line with said clip, said clip tapering in the direction toward said binding post.

3. In a means for securing insulatedconductors, the combination of two binding 5 ductors, the combination of' two binding posts, a. convoluted spring'member having two sockets whose aies are in line with said binding posts respectively, said sockets tapering 'in the direction toward said bind- 10 ing posts.

5. In a means-for securing insulated conductors, the combination of two binding posts, a. convoluted spring member having two sockets whose axes are in line with said binding posts respectively, said sockets tapering in the direction toward said binding posts, and a clamp engaging and contracting both of said sockets. f
